Centrum supplements, graded by the human studies
We graded 2 Centrum products against the human studies of their ingredients, the dose on each label and what buyers say in their reviews. Each grade belongs to the product and the goal it was graded for: we do not grade how Centrum makes, tests or sells its products, and we sell no supplements. Educational, not medical advice.

Questions people ask
Members Only
Is Centrum a good brand?
We grade products, not brands, and we sell none. Of the 2 Centrum products we graded, 1 is Tier 2 (Researched) and 1 is Tier 3 (Reviewed). 2 are top-ranked for the goals they were graded for. Each product's grade, the studies behind it and its label are on its own page.
Which Centrum products have the strongest evidence?
By our grades: Adults (Tier 2, graded for energy); Silver Adults 50+ (Tier 3, graded for immune health). A product's grade is for the goal it was graded for, at the dose on its label.
How does Reverse Age Lab grade Centrum products?
Each product is graded for a goal on the human studies of its ingredients at the dose on its label, what buyers say in their reviews and what our panel of ten biohackers has said. The grade belongs to the product. We do not grade how Centrum makes, tests or sells its products, and we are not affiliated with Centrum.
Can I take Centrum supplements with my meds?
Some supplements can interact with meds. Members have every product checked against the meds in their Health Profile before it joins their protocol.
Educational, not medical advice. Grades come from human studies on PubMed, the dose on each label, store reviews we read ourselves and our biohacker panel, and are updated as new studies arrive. Centrum is a trademark of its owner; Reverse Age Lab is not affiliated with it and sells no supplements. How we grade →
